Personalized Depression Treatment
Traditional therapies and medications don't work for a majority of patients suffering from depression. The individual approach to treatment could be the answer.
Cue is an intervention platform that converts passively acquired sensor data from smartphones into customized micro-interventions for improving mental health. We analysed the best-fit personalized ML models for each subject using Shapley values to identify their feature predictors and uncover distinct features that are able to change mood over time.
Predictors of Mood
Depression is among the world's leading causes of mental illness.1 However, only about half of those suffering from the condition receive treatment1. To improve the outcomes, doctors must be able identify and treat patients who are the most likely to benefit from certain treatments.
The ability to tailor depression treatments is one way to do this. Utilizing mobile phone sensors and an artificial intelligence voice assistant, and other digital tools, researchers at the University of Illinois Chicago (UIC) are developing new methods to determine which patients will benefit from the treatments they receive. With two grants totaling more than $10 million, they will employ these tools to identify biological and behavioral predictors of the response to antidepressant medication and psychotherapy.
To date, the majority of research on factors that predict depression treatment effectiveness has centered on clinical and sociodemographic characteristics. These include demographics like gender, age and education, as well as clinical characteristics such as symptom severity and comorbidities as well as biological markers.
Very few studies have used longitudinal data in order to predict mood of individuals. They have not taken into account the fact that moods vary significantly between individuals. Therefore, it is crucial to develop methods which permit the analysis and measurement of individual differences between mood predictors and treatment effects, for instance.
The team's new approach uses daily, in-person evaluations of mood and lifestyle variables using a smartphone app called AWARE, a cognitive evaluation with the BiAffect app and electroencephalography -- an imaging technique that monitors brain activity. This allows the team to create algorithms that can identify various patterns of behavior and emotions that are different between people.
In addition to these methods, the team developed a machine-learning algorithm to model the dynamic factors that determine a person's depressed mood. The algorithm blends these individual variations into a distinct "digital phenotype" for each participant.
This digital phenotype was found to be associated with CAT-DI scores, which is a psychometrically validated scale for assessing severity of symptom. The correlation was weak, however (Pearson r = 0,08; P-value adjusted for BH = 3.55 10 03) and varied greatly between individuals.
Predictors of symptoms
Depression is a leading reason for disability across the world1, however, it is often misdiagnosed and untreated2. In addition the absence of effective interventions and stigma associated with depressive disorders stop many individuals from seeking help.
To allow for individualized treatment in order to provide a more personalized treatment, identifying predictors of symptoms is important. However, the current methods for predicting symptoms rely on clinical interview, which is not reliable and depression Treatment Effectiveness only detects a limited number of symptoms related to depression.2
Machine learning can improve the accuracy of the diagnosis and treatment of depression by combining continuous digital behavioral phenotypes collected from smartphone sensors with a valid mental health tracker online (the Computerized Adaptive Testing Depression Inventory CAT-DI). These digital phenotypes are able to capture a variety of distinct actions and behaviors that are difficult to document through interviews and permit high-resolution, continuous measurements.
The study included University of California Los Angeles students who had mild to severe depression symptoms who were participating in the Screening and Treatment for Anxiety and Depression program29 that was developed as part of the UCLA Depression Grand Challenge. Participants were sent online for assistance or medical care depending on the severity of their depression. Patients who scored high on the CAT DI of 35 or 65 were assigned online support via an instructor and those with a score 75 patients were referred for psychotherapy in-person.
At the beginning of the interview, participants were asked a series of questions about their personal characteristics and psychosocial traits. The questions asked included age, sex and education as well as marital status, financial status, whether they were divorced or not, their current suicidal ideas, intent or attempts, as well as how often they drank. Participants also rated their level of depression symptom severity on a scale ranging from 0-100 using the CAT-DI. CAT-DI assessments were conducted every other week for the participants that received online support, and weekly for those receiving in-person support.
Predictors of Treatment Reaction
Research is focused on individualized treatment for depression. Many studies are focused on identifying predictors, which will help doctors determine the most effective drugs to treat each individual. Particularly, pharmacogenetics can identify genetic variants that influence how depression is treated the body metabolizes antidepressants. This lets doctors select the medication that are most likely to work for each patient, reducing the amount of time and effort required for trial-and error treatments and eliminating any adverse negative effects.
Another promising approach is to build prediction models that combine information from clinical studies and neural imaging data. These models can be used to determine which variables are most predictive of a specific outcome, like whether a medication can improve symptoms or mood. These models can be used to determine the response of a patient to an existing treatment and help doctors maximize the effectiveness of treatment currently being administered.
A new generation employs machine learning techniques like algorithms for classification and supervised learning such as regularized logistic regression, and tree-based methods to integrate the effects of several variables and increase the accuracy of predictions. These models have been proven to be useful in predicting outcomes of treatment, such as response to antidepressants. These approaches are becoming more popular in psychiatry and will likely become the norm in the future medical practice.
In addition to the ML-based prediction models The study of the underlying mechanisms of depression continues. Recent findings suggest that the disorder is connected with neurodegeneration in particular circuits. This theory suggests that an individualized treatment for depression will be based upon targeted therapies that restore normal functioning to these circuits.
Internet-based interventions are an effective method to achieve this. They can offer an individualized and tailored experience for patients. One study found that a web-based program improved symptoms and improved quality life for MDD patients. Furthermore, a randomized controlled trial of a personalized approach to depression treatment showed an improvement in symptoms and fewer side effects in a significant number of participants.
Predictors of adverse effects
A major obstacle in individualized depression treatment brain stimulation treatment is predicting which antidepressant medications will cause the least amount of side effects or none at all. Many patients experience a trial-and-error approach, with several medications prescribed before finding one that is safe and effective. Pharmacogenetics provides an exciting new method for an effective and precise approach to choosing antidepressant medications.
There are many variables that can be used to determine the antidepressant that should be prescribed, including gene variations, patient phenotypes such as ethnicity or gender and the presence of comorbidities. To determine the most reliable and accurate predictors of a specific treatment, random controlled trials with larger samples will be required. This is because it may be more difficult to detect interactions or moderators in trials that only include a single episode per person rather than multiple episodes over a period of time.
Additionally to that, predicting a patient's reaction will likely require information about the severity of symptoms, comorbidities and the patient's own perception of effectiveness and tolerability. Presently, only a handful of easily measurable sociodemographic and clinical variables seem to be reliable in predicting the response to MDD factors, including age, gender race/ethnicity, SES BMI and the presence of alexithymia, and the severity of depression symptoms.
Many issues remain to be resolved in the use of pharmacogenetics to treat depression. First is a thorough understanding of the genetic mechanisms is needed and a clear definition of what constitutes a reliable predictor for treatment response. Ethics such as privacy and the ethical use of genetic information must also be considered. Pharmacogenetics can, in the long run reduce stigma associated with mental health treatments and improve the quality of treatment. However, as with any approach to psychiatry careful consideration and application is required. The best course of action is to offer patients an array of effective medications for treating depression without antidepressants and encourage them to speak with their physicians about their experiences and concerns.
